Former Toto singer Bobby Kimball is the subject of a documentary that’s in the works, King on a String: The Bobby Kimball Story. There is a Kickstarter campaign to try and raise $30,000, with $17,000 in the can thus far. Kimball, the voice of “Hold the Line,” “Rosanna” and “Africa,” has been diagnosed with frontotemporal dementia. A trailer for the doc is on YouTube.
